Recently - very likely after a system update - when my Computer resumes from Hibernate mode, the clock is wrong. Ofcourse it automatically is set to synchronize in the clock from the server after a week. But it is not used to be this way - it resumed with correct time from Hibrenate. I checked the bios battery - it is fine. When I restarted, the time is correct. My Laptop is Gateway CX2610 Tablet PC running XP Tablet (equivalent to XP Professional) Here is the system info. Item Value OS Name Microsoft Windows XP Professional Version 5.1.2600 Service Pack 3 Build 2600 OS Manufacturer Microsoft Corporation System Manufacturer Gateway System Model CX2610 System Type X86-based PC Processor x86 Family 6 Model 13 Stepping 8 GenuineIntel ~1729 Mhz BIOS Version/Date Gateway 62.07, 4/12/2006 1 person needs an answerI do too
